It's not a conflict of interests, because Pep didn't know that he would benefit from that clause at the time he agreed to become part of the contract. But I know were you're coming from, the fact that Bayern - our main rival next season - will buy Thiago lowcost is very upsetting.
I, choleric as I am, would chop some heads for this charade.
Sorry to be pessimistic, but I doubt we'll be Bayern's main competitor next season. I dont think we're even favourites for our own league title, never mind the Champions League. There are better teams than us out there.
